Game mode: MP
Description:
I used /clear command to clear my chat history. After a few messages my message left only empty space to the bottom line and the message itself popped up on the many lines above. This happened occasionally for some messages, for everyone who had done /clear command.
Steps to reproduce:
Start MP game (you might need some players in it I'm not sure), make /clear command and then send messages.
